The apps that are developed and run on the Old Windows Phone OS are called the Silverlight apps and as per a leaked screenshot fromÂ Gustave M shows a notification about Microsoft dropping support with the further releases of Windows 10 Mobile OS .

This means that the apps like WhatsApp wont be able to work on the Windows 10 Mobile OS’s future versions unless a UWP Windows 10 App is released . Also, this shows the commitment of Microsoft with Windows 10 Mobile and UWP especially.

It is also worth noting that devices like the Microsoft Lumia 535 which were not eligible for Windows 10 Mobile Creators Update will not be affected by this change and will be able to enjoy the UWP apps (if the SDK Version Matches) else will be able to use the old Silverlight apps without any issues.
